Detailed Description of Steel-plastic fittings Rubber Ring Joint:

For steel-plastic pipe fittings, in the small diameter range, that is, for pipe fittings with a diameter of ф63-ф200, standard seamless steel pipes will be selected. For pipe fittings with a diameter of ф225-ф1200, the thickness of the steel plate will be accurately determined according to the size of the socket. Common thickness specifications include 6mm, 8mm, 10mm, and 12mm. The steel plate is formed through a curling process and then welded.
After the pipe fittings are formed and welded, they go through the grinding and sandblasting process to remove the protrusions and burrs left by the welding and enhance the adhesion for the subsequent plastic spraying process. Then, the key electrostatic plastic spraying process is carried out, and the plastic powder is evenly sprayed on the inner and outer walls of the pipe fittings. This process adopts advanced electrostatic spraying technology, using the principle of electrostatic adsorption to make the plastic powder adhere closely to the surface of the pipe fittings.

Characteristics and Advantages of Steel-plastic fittings Rubber Ring Joint

1. High Strength and High Toughness: With high-strength carbon steel as the base body, the steel has excellent strength and toughness, endowing the steel-plastic pipe fittings with good compressive capacity. They can withstand large internal fluid pressure and external mechanical forces.
2. Excellent Corrosion Resistance: The plastic coating on the inner and outer walls of the pipe fittings has strong tolerance to various chemical substances. It can effectively resist the corrosion of media such as acids, alkalis, and salts, avoiding problems such as pipeline perforation and leakage caused by corrosion.
3. Good Wear Resistance: The wear-resistant characteristics of the plastic enable the steel-plastic pipe fittings to exhibit better wear resistance than ordinary steel pipes when transporting fluids containing solid particles.
4. Hygienic and Non-toxic: The selected plastic materials usually meet the hygiene standards and will not release harmful substances into the transported fluids, ensuring the purity and safety of water quality and other fluids.
5. Smooth Inner Wall and Low Fluid Resistance: The plastic coating makes the inner wall of the pipe fittings extremely smooth. Compared with ordinary steel pipes, it can effectively reduce the resistance when the fluid flows inside the pipeline, reducing the transportation energy consumption and improving the transportation efficiency.
6. Good Insulation Performance: Plastic is a good insulator, so the steel-plastic pipe fittings have excellent insulation performance, which can effectively avoid potential safety hazards caused by current conduction.
7. Good Weather Resistance: The plastic coating can withstand the influence of natural environmental factors such as ultraviolet rays, high temperature, and humidity, and is not easy to age, discolor, or be damaged.
8. Convenient Connection: The steel-plastic pipe fittings can adopt a variety of connection methods, such as socket seal ring connection, flange connection, etc. The operation is simple and quick, and the connection is firm and reliable. It can meet the installation requirements of different engineering sites and improve the construction efficiency.
9. Strong Design ability: According to different usage requirements, parameters such as the material and wall thickness of the steel pipe base body, and the type and thickness of the plastic coating can be flexibly adjusted to customize steel-plastic pipe fittings that meet specific performance requirements, so as to adapt to diverse engineering application scenarios.
